Spectral Properties of the Harary Signless Laplacian and Harary Incidence Energy

open access: yesMathematics
Let X be a partitioned matrix and let B its equitable quotient matrix. Consider a simple, undirected, connected graph G of order n. In this paper, we employ a technique based on quotient matrices derived from block-partitioned structures to establish new
